I am a Ph.D. student at the Sussex Centre for Consciousness Science, University of Sussex, supervised by Anil Seth and Christopher Buckley, and a research fellow at the AI Alignment Network in Tokyo.

Ryota Takatsuki

I study transformer-based language, vision, and vision–language models as comparative experimental systems for consciousness science. My work asks whether these models exhibit consciousness-associated phenomena, such as bistable perception and metacognition, and uses mechanistic interpretability to characterize how they are implemented. I see this as one tractable route into which sentience-relevant functions AI systems may already approximate, and which they do not.

Before Sussex, I was a research intern in Ryota Kanai’s research team at Araya Inc., where I worked on meta-representations as a way of operationalizing higher-order theories of consciousness for deep learning models, alongside the mechanistic interpretability of visual illusions. I also studied bistable perception in multimodal models at the R&D Center for Large Language Models, National Institute of Informatics, and real-time 3D video transmission at the University of Tokyo, where I completed my B.S. in Systems Innovation.
